ATTACHMENT DEVICE.

Application Itiled January 11, 1921. Serial No. 438,589.

To all whom t may concern.'

Be it known that I, HARRY BEnnow, a citizen of the United States,residin at New York, county and State of NewY ork, have invented certainnew `and useful Improvements in Attachment Devices, of which thefollowing is a specification.

This invention relates to an attachment device lfor cleaning mops andbrushes and lprimarily aims to provide a medium for detaching such mopsand brushes readil and, which at the time when attached, will maintain afirm and rigid handle.

Other objects as well as the nature, characteristic features and scopeof my invention will be more readily understood from the followingdescription, taken in connection with the accompanying drawings andpointed out in the claims forming a part of this specification.

Figure 1 of the drawing, representing by way of example a practicalembodiment of the invention, is a side elevationl of the improvement.

Figure 2 is a sectional side elevation of the improvement and Figure 3`is a crosssectional view on the line 3 3 of- Fig. 1; Fig. 4 shows bothparts of the joint separately, the slotted tube as a side elevation andthe other part, containing the pressure coil, as a sectional view; Fig.5 finally repreents a perspective view of the slotted tu e.

As illustrated in Figure 1 an object in the form of a cleaningmo is heldby a wire rope 2 secured with its ree ends within the smooth end of tube3 which at its other end is provided with a slot 4 having an extension 5at right angle with slot 4 and the further extension 6 bein parallelwith yslot 4, the slots 4, 5 and 6 t erefore forming a kind of hook likeincision into tube 3. A similar system of slots 7, 8 and 9 are provideddiametrically opposite. to slots 4, 5 and 6, with the difference howeverthat slot 8 runs in the opposite, direction from that of slot 5 and thatconse uently also slot 9 is located oppositel to s ot 6. Tube 10 is bentat approximately its middle and aiiixed to the end 14 of handle 12. Apin 13 is rigidly secured within tube 10 at a distance` whichcorresponds approximately one half of the length of slot 4. Between theend 14 of handle 12 and pin .13 within the tube 10 there is a plate 15movably4 arranged, a spring 16 being furthermore interposed between saidplate 15 and end 14 of handle 12.

In case I do not use the cleaning device I detach' tube 3 with lthe mopproper from the handle and store each part in any manner convenient tome; if I want to use the device I slip'tube 10 over tube 3 which fitstelescopically into the former, and as pin 13 enters the slots 4 and 7it is obvious that fromA this moment the rim 17 of tube 3 presses late15 against spring 16 which recoilst ereby. As soon as pin 13 has passedthe full length of slots 4 and 7 the handle 12, or tube 10,respectively, is turned byY a twist of the hand to pass pin 13 throughslots 5 and 8 andl after they are passed spring 16 extends again topress pin 13 against the e-nds of slots 6 and 9. It is obvlous thereforethat tube 3 is held by three diiferent means to tube 10, by the wall oftube 10, by the rear ends of the bayonet slots 6 and 8, which spring 16presses a ainst pin 13, and by the plate 15, same eing pressed againstrim 17 of tube 3 by spring 16.

Having now I claim is:

1. An attachment device of the character as described, consisting of ametal tube having at one end diametrically opposite to each other twoslots, having their hook sha ed ends running in opposite directions, anat the other end the ends of a wire rope rigidl secured therein, anothertube telescopical y fittin over the tube referred to above,

in rigi y secured within the latter tube, a andle secured to same, anannular late movably arranged within said tube be ind the pin, and aspring interposed between said plate and the handle.

2. As a new article of manufacture an attachment device of the characteras described, consisting of a metal tube having at one end diametricallyopposite to eac other two slots having their hook shaped ends running inopposite directions, and at the other the ends of a wire rope rigidlysecured therein, another tube telescopically fitting over the tubereferred' to above, a pin rigidly secured within the latter tube adaptedto enter the ends of the aforesaid hooks, a handle secured to aforesaidtube, an annular late movably arranged within said tube be ind the pin,and a spring interposed between said late and the handle..
